Combination

Combination operators in RxJS are used to combine multiple observables into a single observable. There are several types of combination operators, including:

  • Merge: merges multiple observables into a single observable that emits items from each source observable in a sequence.

  • Concat: concatenates multiple observables into a single observable that emits the items from each source observable in sequence, one after the other.

  • Zip: combines the items from multiple observables into a single observable by combining the items from each observable at a corresponding index.

  • CombineLatest: combines the latest values from multiple observables into a single observable by emitting an item whenever any of the source observables emit an item.

  • WithLatestFrom: combines the latest value from one observable with the latest values from multiple other observables.

  • ForkJoin: combines the items from multiple observables into a single observable by emitting an item only after all of the source observables have emitted an item.

Further documentation can be found in the official RxJS documentation:
